Each one of those three missiles costs 33% more than the annual budget of the national park where I work.

So Israel is launching a "preventive" strike on Iran and also announcing a state of emergency, because they expect Iran to respond to their "preventive" strike by launching missiles. So like... what's being prevented here?

Historical deforestation drives strong rainfall decline across the southern Amazon basin - Nature Communications The authors find that historical deforestation has substantially altered regional observed precipitation over the southern Amazon basin through inter-regional atmospheric moisture transport, which is ...

Land-atmosphere feedbacks mean that major Amazon deforestation is causing substantial downstream rainfall reductions.

New analysis in @natcomms.nature.com combines novel theoretical understanding with data to quantify feedbacks.

Saltmarsh on Wallasea Island at high tide

Saltmarsh on Wallasea Island at high tide

New UKCEH research shows UK saltmarshes are significant carbon sinks, storing ~6.5 t COβ‚‚e ha⁻¹ yr⁻¹, comparable to mangroves and seagrasses.

Saltmarshes aren't yet included in the UK GHG Inventory, but the evidence base is strengthening.

Frequently asked question:

β€œHey David, I’ve seen you arrange shark research field skills courses and one-day expeditions for a variety of universities and organizations. Could you do that for my group?”

Absolutely yes! Let’s chat.

Study: Oil companies are not β€˜part of the solution’ New research in the journal Nature reveals oil and gas companies own a β€œmarginal” share of global renewable capacity, years after claiming they would lead the energy transition.

"The first-of-its-kind study shows that the world’s biggest oil and gas companies contribute less than 1.5% to global renewable energy β€” contradicting industry claims to be pioneers in the energy transition."

Really cool this! New insight into where museum specimens come from is always welcome, would love to be able to apply it to egg collections (many of which are unlabelled due to their collectors being old, bored, 19th century toffs who were only in it for aesthetic value and prestige).

I have a fundamentally different political view to that entire March today.

But I am fucking sick of the rank classist comments eg referencing things like "flat roof pubs" and Wetherspoons when talking about it.

Stop painting working class people as stupid racists;

My rent's gone up by almost 20% - and my landlord wants to evict me Glasgow tenant Elle Glenny says the impact of a rent increase has been catastrophic.

"The landlord says the rent increase reflects the market rate for the area."

Translation: "Every other landlord round here is hiking the rent, so I reckon I can get away with it too."

This is exploitation, plain and simple. We need robust rent controls now.

The men are shit, the women are shit, the Union’s full of cunts, your club’s about to be cut, and it honestly feels like it’s only going to keep getting worse. Welsh Rugby in 2025 is the pits.

Brazil authorities suspend key Amazon rainforest protection measure Suspension of Soy moratorium could open up area of rainforest the size of Portugal to destruction

Forests are vital in fighting climate change. 🌲

The Amazon Soy Moratorium has been one of the greatest successes in halting #deforestation since its implementation in 2006.

Scrapping it sends the wrong signal ahead of #COP30 and threatens the Amazon. ❌

Our paper is already one of the ten most-shared on social media articles in the history of the journal.

As of right now, 14 people have posted about it on Twitter.

And 1,018 people have posted about it on Bluesky.

Which sorta makes our point here?
